Cellulose Insulation

What Is Cellulose Insulation

Cellulose insulation is manufactured primarily from recycled paper fibers and treated with borate compounds for fire resistance and pest deterrence. These treatments improve safety and durability while maintaining a low environmental impact.

Because of its density, cellulose fills cavities more completely than many loose fill insulation products, helping reduce air movement and sound transmission.

Key Benefits of Cellulose Insulation

Environmental responsibility
Cellulose insulation contains a high percentage of recycled material, reducing landfill waste and supporting sustainable building practices.

Fire resistance
Borate treatment provides fire resistance and allows cellulose to meet Class A fire performance standards.

Pest deterrence
The same borate treatment discourages insects and rodents from nesting within the insulation.

Sound control
Dense cellulose fibers absorb airborne sound effectively, making it a strong choice for noise reduction between rooms and floors.

Common Applications for Cellulose Insulation

Cellulose insulation is well suited for specific residential applications, including:

Attic blow over installations
Cellulose can be added over existing insulation to improve overall thermal performance without major structural changes.

Wall retrofits
Dense pack cellulose can be installed into existing wall cavities with minimal disruption, making it effective for older homes.

Sound focused assemblies
Because of its density, cellulose performs well in interior walls where sound reduction is a priority.

Addressing Settling and Long Term Performance

Settling is a common concern associated with cellulose insulation. When installed improperly or at insufficient density, settling can reduce effectiveness over time.

When dense packed correctly by trained installers using high output blowing equipment and proper density calculations, settling is minimized and long term performance is maintained.

Structo Insulation follows controlled installation standards to ensure cellulose insulation remains stable and effective for the life of the building.

Choosing the Right Insulation System

Cellulose insulation is one of several insulation options available. Its performance depends on proper application and the specific conditions of the building.

During an insulation evaluation, Structo Insulation reviews the structure, existing insulation, air leakage, and performance goals to determine whether cellulose is the appropriate solution or whether another insulation system would provide better results.

Request a Cellulose Insulation Evaluation

If you are considering cellulose insulation for an attic upgrade, wall retrofit, or sound control application, an evaluation can help determine whether it is the right choice for your home.

Request a cellulose insulation evaluation to review your options and develop an insulation plan that aligns with your performance and comfort goals.
